The LDW-R7 series answers a different question than the five- and six-axis machines elsewhere in this catalog. Those are machine-tool platforms: a column, a worktable, and travel axes that determine what the machine can reach. Here the working unit is an industrial robot arm carrying a deburring and polishing spindle at its wrist, with a working range of \u00d81600 mm. Reach and access come from the arm’s articulation rather than from axis travel, which changes the economics of complex geometry: a part with burrs on five sides, deep pockets, or reversing contours is reached by reorienting the wrist, not by re-fixturing the part.<\/p>\n
The trade is precision. The cell holds \u00b10.05 mm, against \u00b10.02 mm\/300 mm for the machine-tool builds in the same catalog. For the great majority of deburring, edge breaking, and surface finishing work, that is comfortably sufficient, because the tolerances that matter are edge condition and cosmetic quality rather than machined position. Where a print calls for gauge-controlled machined datums, the machine-tool platforms are the better tool, and the selection guide linked below draws that line explicitly.<\/p>\n
An R7 cell stacks four elements: the robot arm, the spindle it carries, the fixtures on the workstations, and the guarding and controls around them. The spindle runs from 3000 to 24000 RPM and is offered at 2.2, 3.5, or 5.5 kW, oil-cooled for stability at high speed with low vibration and long bearing life. Tools clamp from \u03a63 to \u03a613 mm, covering carbide burrs, chamfer mills, mounted points, flap wheels, and brush packs for both deburring and polishing steps on one part.<\/p>\n
Control is selectable among Mitsubishi, KND, and Taiwan Xindai, all mature industrial systems, and the choice usually follows a plant’s existing standard, maintenance familiarity, and budget rather than any process difference. A handwheel ships as standard for setup and recovery, and automatic lubrication carries the cell through long production runs. Two mechanical configurations define the range: the LDW-R7-2, a single robot serving two stations, and the LDW-R7-3, the robot clamping tool layout with three stations.<\/p>\n
Programs are taught rather than coded: the operator guides the tool along the part once, and the path is stored and recalled by workpiece. Because the arm holds the tool, changing part families usually means changing fixtures and recalling another taught program, not re-engineering the machine.<\/p>\n

Cells are fitted with storage bins for raw and finished parts, and the stations keep loading and unloading out of the machining cycle. In practice one operator manages five to ten units, responsible only for handling material, while the robots run their taught programs continuously. That is the pattern that replaces a bench of ten manual deburring stations with a robot row and one person, and it is the reason the R7 fits plants whose pain is staffing and consistency rather than cycle time.<\/p>\n Where a part needs tighter precision or heavier milling stock removal, the machine types guide<\/a> explains when the five-axis and six-axis platforms take over.<\/p>\n Two guides frame the decision this page sits in. What Is Robotic Deburring?<\/a> covers the process itself, tool selection, force and speed considerations, and what moving from manual benches to a robot cell changes on the shop floor. The Types of Deburring Machines: Complete Selection Guide<\/a> compares robot-held-tool cells against machine-tool-style equipment across precision, geometry, and volume, which is precisely the comparison an R7 buyer is making.<\/p>\n |
